OESA-2026-1731 pyOpenSSL security update

pyOpenSSL is a rather thin wrapper around a subset of the OpenSSL library. With thin wrapper we mean that a lot of the object methods do nothing more than calling a corresponding function in the OpenSSL library. Security Fixes: A security vulnerability exists in the PyOpenSSL library's...

Buffer Overflow

pyOpenSSL is vulnerable to Buffer Overflow. The vulnerability is due to improper bounds checking in setcookiegeneratecallback, where cookie values exceeding 256 bytes can overflow an OpenSSL buffer, potentially leading to memory corruption...

CVE-2026-27459

A flaw was found in pyOpenSSL. The setcookiegeneratecallback callback function can be used to generate DTLS cookies. When the callback returns a cookie string or byte sequence longer than 256 bytes, a buffer overflow can be triggered due to a missing bounds checking before copying the data to a...

DEBIAN-CVE-2026-27459

pyOpenSSL is a Python wrapper around the OpenSSL library. Starting in version 22.0.0 and prior to version 26.0.0, if a user provided callback to setcookiegeneratecallback returned a cookie value greater than 256 bytes, pyOpenSSL would overflow an OpenSSL provided buffer. Starting in version 26.0....

curl 资源管理错误漏洞

curl is a tool for transferring data from or to a server. A resource management error vulnerability exists in curl versions 7.71.0 through 7.83.1, which stems from curl's lack of a limit on the size of the Set-Cookie in generated HTTP requests. An attacker could exploit this vulnerability to...
